Beitknovvn thatI, JOHN NEGRESCOU, a

citizen of'the United'States, and a'resident of F Chica o,'- in the county of Cook and- State of llinois','-have invented certain new and useful Improvements in VVashing-Ma'a chines, of'which the follotving'is a specification'. Hy invention relates to improvements in i washing machines, and" more particularly tothe class of washmg machines fully set forth in the prior application filed by me in the United States-Patent Officebn the 4th day of October, 1918;and hearing se- 'rial Ida-256,784.

The present invention --per-tains more especial-ly to a' combination of members which. serve as a safety device to prevent inj-ur y to the clothes and water-containing receptacle, by the- -opera'tion of the gas burner or other heating-"element provided beneath the tub forheating the Water therein during. the

the discharge of the ater therefrom.

The features-embodying my invention are hereinafter set forthin detail and fully disclosed in the acompanying drawings, in Wl11C l1" Figure l is a View in elevation of the Washing machine showing": the parts embo'd'ying the -invention,- and FigJQ'is a vdeta-il vlew 1n sectlonytaken on line 2, 2 of F-1'g.--1.-'

In order that a thorough understanding ma be had-of the Washing machine to which this invention relates, the principal parts and mode of operation 1 will be set forth; The machine comprises 111 general a cylindric shaped "tub 'l imoun'ted in -vertical shaft "7.- bearinghox Sm'ounted-m the topi wall t of position upon legs2,-2', said 'tub having a removablecover 3extending over substan-' tially one-half the top 5 thereof, the I'Gmilllif ing portion of" the top" being permanently I closed by a'w'all 4" upon vhich yis mounted certain operating members hereinafter to' be described; WVithi'n' the receptacle '1 is a cylindric-shaped basket "5g the same being secured toa frame figivhich in turn is mounted upon a Vertically arranged hollow The shaft/7 is joi'1rnaledj Within a the receptacle there being keyed to'the' up- The basket 5 is also journaled upon the botfixed theretora: pulley 15.

5105 '7 The shifting-from 'on'e'operati'onsto the other is accomplished by shifting the drive belt 26 from the pulley 15 to the pulley 13, and

vice versa, said belt 26 being carried by a pulley'driven by a suitable motor mounted at the base of the machine. ing device consists of an endwise movable bar 28 which engages the belt at its outer end and a shifting lever 29 being provided with a toothed sector 29 at its lower end, which meshes with a rack 28 formed in the shifting bar 28. Intermediate the pulleys 13 and is preferably provided an idler pulley 30 to which the belt may be shifted V if it is desired to stop the operation of the 20 plying gas to the burner.

adjacent to the burner is a valve 33 promachine without shutting off. the motor.

For the purpose of heating the water within the receptacle or tub I there is provided a gas burner 31 located beneath and adjacent to the bottom wall of the tub. The burner 31 may be of any. suitable type and have connected therewith a pipe 32 for sup- In the pipe 32 :and

vided with a valve handle 34 preferably extending in a direction to the left, as shown in Fig. 1 of the drawing, and arranged to occupy a, horizontal position when the gas valve is closed.

-Adjacent to the burner 31 of the heating apparatus is the water discharge passage 35 which communicates with the tub 1 and serves as a means for drawingoff-or discharging the water from the tub after the clothes have been cleaned and p'riorto the.

drying operation. It isto be pointed out that it is more desirable andeconomical to use the same .water for several qualities of clothes, therefore the water is discharged vinto a separate receptacle 36 immediately below the tub 1. The passage 35 consists of a pipe andra discharge fitting 37 having a valve 37 therein, said valve being provided with'an operating lever 38 adapted to occupy a horizontal position whenthe valve is open and to extend in the direction of the heating apparatus. The relation of ..the gas valve handle 34 and the water discharge Valve lever 38 is clearly shown in Fig. 2, said members being substantially parallel to each other, the'lever 38 overlapping said valve handle 34 and in contact therewith through the medium of a lug, or projection 39 formed at ,theend of the lever 38. V

As before suggested,-the gas valve 33 is in closed position when its valve handle 341 is in horizontal position, whereas the water discharge valve is open when'its operating lever is in horizontal position and in contact withthe valve handle 3 1. It is evident that so "long as the-discharge valve is open the gas willbe shut off, hence the person will not inadventently light the burner so long as there is no water .in the tub. Similarly if thejburner is. lighted and a quantity of water is ,within'the tub, both members 34' V and'38 will be in raised position and in the The belt shift- I act of discharging the water from the tub the valve lever 38 will be moved downwardly to open position and in so doing will come in contact w th the gas valve handle 34; and automatically close the same, thus extinguishing the burner;

This arrangement provides a simple yet exceedingly desirable safety device which insures the protection of the tub and contents by making it impossible for the burner to remain lighted under the tub when there is no water therein.

Although I have describedand illustrated the preferred embodiment of the-invention,

it is manifest that the same may be considerably modified without departing from the spirit of the invention, therefore I do not wish tobe limitedexcept so far as I have expressly defined the invention in the 'appended claims. 7 I I I claim as my invention: 1; Inawashing machine, the combination ofa tub provided with a liquid discharge valve and a valve operating member, a heat:
